NOMA, a prominent multiple access scheme in modern wireless communication systems, facilitates concurrent transmission of multiple users over the same time-frequency resource. However, NOMA is susceptible to elevated PAPR, causing efficiency degradation and inter-symbol interference. The proposed method leverages SLM to address the PAPR challenges in NOMA waveforms. By generating a set of diverse phase sequences, SLM constructs alternative versions of the original NOMA signal. The phase sequence resulting in the lowest PAPR is then selected for transmission. This dynamic adaptation significantly reduces the peaks in the transmitted signal, thereby enhancing efficiency, minimizing distortion, and reducing the risk of nonlinear amplification. Extensive simulations are conducted to evaluate the efficiency of the projected procedure. The results demonstrate remarkable PAPR reduction in NOMA waveforms compared to conventional transmission methods. Additionally, the method maintains signal quality, improving the Bit Error Rate (BER), Power spectral density (PSD) and enhancing the overall reliability of the radio framework. The paper concludes with insights into the feasibility of integrating SLM into existing NOMA-enabled systems, offering a promising avenue for optimizing the efficacy of advanced radio networks.","PeriodicalId":233627,"journal":{"name":"Известия высших учебных заведений.

As a result, 6G network research has already seen participation from both the private sector and the academic community. Recently, a innovative paradigm has emerged for the intelligent design and optimization of 6G networks, based on the combination of artificial intelligence (AI) and data science (DS). Therefore, this article proposes an AI-enabled architecture for 6G-networks, which is alienated into four layers: an intelligent-sensing, a data-analytics, intelligent-control and smart-application, with the goal of realizing patterns sighting, smart-resource management, automatic network adjustment, and intelligent-service provisioning. We then go over the uses of DS&AI methods in 6G networks, such as AI-enhanced mobile edge-computing, intelligent-mobility, and smart-spectrum management, and go into detail about how to implement these methods to maximize the network's performance. We also emphasize key areas for future study and possible clarifications for AI-enabled 6G networks, together with as computational efficiency, algorithm resilience, hardware-development, and energy-management.","PeriodicalId":233627,"journal":{"name":"Известия высших учебных заведений.

Furthermore, the approach utilized to obtain insights from the scrutiny of lifestyle elements and activities is crucial to the success of tailored healthcare and disease prevention services. Intelligent data retrieval and classification algorithms allow for the investigation of disease and the prediction of aberrant health states. The Convolutional-neural-network(CNN) strategy is utilized to forecast such anomaly because it can successfully recognize the knowledge significant to disease anticipation from amorphous medical heath records. Conversely, if a fully coupled network-topology is used, CNN guzzles a huge memory. Furthermore, the complexity analysis of the model may rise as the number of layers grows. Therefore, we present a CNN target recognition and anticipation strategy based on the Pearson-Correlation-Coefficient(PCC) and standard pattern activities to address these shortcomings of the CNN-model. It is built in this framework and used for classification purposes. In the initial hidden layer, the most crucial health-related factors are chosen, and in the next, a correlation-coefficient examination is performed to categorize the health factors into positively &negatively correlated groups. Mining the occurrence of regular patterns among the categorized health parameters also reveals the behaviors of regular patterns. The model's output is broken down into obesity, hypertension, and diabetes-related factors with known correlations. To lessen the impact of the CNN-typical knowledge discovery paradigm, we use two separate datasets. The experimental results reveal that the proposed model outperforms three other machine learning techniques while requiring less computational effort.","PeriodicalId":233627,"journal":{"name":"Известия высших учебных заведений.

One of the powerful enabling tools of the 5G communication systems is the Multi-Input Multi-Output (MIMO) antenna system employing multiple antennas and utilizing the multipath fading mobile environment to increase the channel capacity without any additional bandwidth and/or transmitted power. However, because of the limited space of the mobile devices, the distances between antennas are decreased. The mutual coupling between antennas severely affects the overall performance of the MIMO system. So, isolation improvement methods are applied to reduce these influences. In this review, the different isolation techniques and their features and drawbacks are presented, and the techniques for applying them in modern MIMO antenna systems are illustrated. Besides, the performance characteristics of these MIMO systems are compared. The review contains also the basic concepts of the MIMO antenna system and its performance metrics. Finally, the future directions and trends for the MIMO antenna system design are discussed briefly.","PeriodicalId":233627,"journal":{"name":"Известия высших учебных заведений.

При цьому досягається узгодження входу і виходів пристрою з високим рівнем розв’язки останніх. Запропонована структура складається з каскадного з’єднання чотирьох відрізків зв’язаних ліній, двох реактивних елементів, що реалізуються шлейфами, і ланки розв’язки виходів, для реалізації якої приведено три варіанти схем.

Крім того, в процесі розрахунку враховується різниця фазових швидкостей мод мікросмужкових зв’язаних ліній. Для перевірки властивостей запропонованої схеми та методу її проєктування виготовлено та експериментально досліджено мікросмужковий балун на дві робочі смуги частот з середніми значеннями 1,4 ГГц і 2,8 ГГц при різних комплексних опорах навантаження. Результати вимірювань добре узгоджені з результатами електромагнітного моделювання і показують, що в обох смугах розбаланс амплітуд і фаз на виходах балуна не перевищує 1 дБ і 10 градусів відповідно, підтверджуючи доцільність використання запропонованої схеми та методу її проєктування.","PeriodicalId":233627,"journal":{"name":"Известия высших учебных заведений.

The arrival of 5G, however, is seen as a watershed moment that will radically alter the current global trends in wireless communication practices and the lives of the masses. 5G envisions a future where the digital and physical worlds merge. The 6th-generation (6G) wireless communication network will likely unite terrestrial, aerial, and maritime communications into a single, unified system that is both more stable and faster, and can accommodate a far larger number of devices with ultra-low latency needs. This research hopes to foresee a scenario in which 6G supersedes 5G as the dominant standard for wireless communication in the years to come. Several advances have been made, but the utopian period of instantaneous global communication, instantaneous global computation, and no latency has not yet arrived. This essay investigates the most significant obstacles and difficulties that the transition from 5G to 6G may encounter on the way to realizing these loftier goals. The vital goal of \"technology for humanity\" is to improve service to the world's most disadvantaged people, and this article lays out a plan for 6G that includes the enabling technology infrastructures, obstacles, and research directions that will get us there.","PeriodicalId":233627,"journal":{"name":"Известия высших учебных заведений.
